Apple's security update train rumbled into the station late May 11 with fixes for a whopping 43 Mac OS X and QuickTime vulnerabilities. The company's Security Update 2006-003 patches 31 flaws in the Mac OS X, most of them serious enough to cause 'arbitrary code execution attacks'. Apple also shipped QuickTime 7.1 as a major security overhaul to correct 12 code execution and denial-of-service flaws.
